Error doing an index block split on “<fn ft fm>“, RC=<rc>, USER=<lid>

Reason

CA ACF2 for z/VM found an error when inserting a record and trying to split a full index block into two index blocks.

<fn ft fm>: The CMS file ID of the database
<rc>: The return code
<lid>: The user that invoked the function doing this I/O request.

Action

If the return code was 13, there were no more available blocks left to add a new index block. The file needs to be expanded, although backing it up and restoring it can clean up enough space by restructuring the data in the file.

For return codes other than 13, there should have been a previous error message indicating why a particular FSWRITE failed, that resulted in the index block split function failing.
